Patent number: 10611039Abstract: A camera for observing the inside of a shielded cell comprises a support provided with a spring in the form of a gripper for mounting it on a remote- manipulation arm performing the task to be observed, by means of another arm, exerting solely a force for opening the branches of the spring, after which the camera is properly held, while being able to be removed without difficulty. A stop means is added in order to provide the correct angular position of the camera while preventing its support from turning about the arm, and thus making it possible to position it correctly by other remote-manipulation means.Type: GrantFiled: March 16, 2015Date of Patent: April 7, 2020Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Francois Gobin, Mickael Gennisson, Christophe Brenneis

Patent number: 10112358Abstract: A uniaxial press for shaping pellets by compressing powder in a die by punches. The uniaxial press can be used in a restricted and hostile environment and includes small modules that can pass separately through narrow openings, the modules being assembled by placing over columns and by screwing, therefore by remote handling in the confined space where the press is to operate without requiring any further intervention. The actuation is generally exclusively electromechanical.Type: GrantFiled: May 26, 2015Date of Patent: October 30, 2018Assignees: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVES, CHAMPALLEInventors: Jean-Philippe Bayle, Patrick Moyer, Christophe Brenneis, Patrik Gosset, Patrick Baptiste, Didier Lager

Patent number: 9046610Abstract: A mechanical device for supporting and attaching at least one ionizing radiation detection probe. For each detection probe it includes one probe-holder ending in a collimator-holder able to support a collimator intended to delimit a field of observation of the detection probe, and an attachment device intended to be attached to a glove port of a glove box, where the probe-holder, or each probe-holder, cooperates with the said attachment device.Type: GrantFiled: June 20, 2011Date of Patent: June 2, 2015Assignee: Commissariat a l'energie atomique et aux energies alternativesInventors: Christophe Brenneis, Christian Ducros, Fabrice Lamadie, Philippe Girones

Patent number: 8663353Abstract: A filter including multiple tanks connected in series by connecting ducts. In the filter a flow of gaseous flows encounters multiple obstacles in it, an effect of which is efficiently to block constituents with heaviest molecular weight, without substantially hindering diffusion of lighter constituents. This may be obtained by internal baffles, or by a bank of finer ducts, for example at an inlet of the filter. Such a filter may find application to separation of hydrogen and radon produced by nuclear waste.Type: GrantFiled: March 17, 2011Date of Patent: March 4, 2014Assignee: Commissariat a l'Energie AtomiqueInventors: Pierre De Coninck, Christophe Brenneis, Guillaume Ranc

Patent number: 8507861Abstract: A radiological characterization device comprising at least one collimated radiological measuring probe, a sensitive end of which is placed in an exchangeable collimator having an opening and a field of observation. The collimator is carried by a collimator holder, the assembly consisting of collimator and collimator holder being inserted in a stack between two shielding screens, the shielding screens being exchangeable so as to adjust the thickness thereof, the assembly consisting of collimator and collimator holder and the shielding screens providing protection for the probe vis-à-vis parasitic ionizing radiation coming from ionizing radiation sources situated outside the field of observation of the collimator.Type: GrantFiled: March 11, 2010Date of Patent: August 13, 2013Assignee: Commissariat a l'Energie Atomique et aux Energies AlternativesInventors: Philippe Girones, Christophe Brenneis, Fabrice Lamadie, Christian Ducros
